iOS 6 Portrait Fullscreen via iBackupBot

Hi guys.I was wondering is it possible to enable portrait fullscreen in iOS 6 by changing plist files like old days with no jailbreak required.Since it's a iOS feature but probably disabled for portrait, I hope that someone can find the plist file we need to modify.Some people managed to enable battery percentage on ipod touch and multitouch gestures on ipad by this way.I also added some old threads' links to the post.
Thanks, Birkan

Yes, that's a possibility but I think that's too early to say it can't be done.I just posted that thread for people to saw that so when next time they saw something about that subject they can reply to this thread.In the end everyone will benefit
